  • The Science Behind 128/32 Quartz Crystal Oscillators

    Quartz crystal oscillators are the most widely used frequency control components in electronic circuits. They serve as a stable, high precision reference for frequencies ranging from a few kilohertz to hundreds of megahertz. The fundamental quartz crystal is the basis for these highly precise oscillators and has been in use for over a century.

    Let’s discuss and figure out the science behind 128/32 quartz crystal oscillators, specifically looking at the technology used by EPSON to achieve such high precision.

    The Fundamental Quartz Crystal

    One of the key advantages of using quartz crystals in electronic circuits is their ability to maintain a constant frequency over a wide range of temperatures. This stability is crucial in applications where precision and accuracy are critical, such as in timekeeping devices or communication equipment. Additionally, quartz crystals have very low levels of electrical resistance, making them highly efficient for use in oscillators.

    Aside from their use in electronic circuits, quartz crystals also have a variety of other applications. They are commonly used in watches and clocks as the timekeeping component due to their precise frequency. They are also utilized in sensors for various industries such as automotive, aerospace, and medical fields.

    Quartz crystals can even be found in everyday devices like smartphones and computers where they help maintain accurate timing and synchronization. With their unique electrical properties and versatility, quartz crystals continue to play a vital role in modern technology.

    EPSON’s Advanced Technology

    EPSON, a leading manufacturer of quartz crystal oscillators, has developed advanced technology to produce 128/32 quartz crystal oscillators with exceptional precision and stability. These oscillators are designed for applications that require high accuracy such as cellular base stations, GPS, and satellite communication systems.

    So, what makes EPSON’s technology stand out?

    Temperature Compensation

    One of the main factors that affect the accuracy of a quartz crystal oscillator is temperature. As temperature changes, so does the frequency of the crystal.

    To combat this, EPSON uses their patented Temperature-Compensated Crystal Oscillator (TCXO) technology in their 128/32 oscillators.

    This technology combines a thermistor with the quartz crystal to create a temperature feedback loop that adjusts the frequency to compensate for any temperature changes.

    This results in a highly stable oscillator that maintains its accuracy even in extreme temperature conditions.

    Frequency Trimming

    To achieve even higher precision, EPSON utilizes Frequency Trimming technology in their 128/32 oscillators. This involves adjusting the frequency of the crystal by removing tiny pieces from its edges. This process is done using laser trimming, which allows for precise and accurate adjustments without damaging the crystal.

    With this technology, EPSON can achieve a precision of up to ±0.5 ppm (parts per million), which means that the oscillator will deviate by only 0.5 Hz per million Hertz of output frequency.

    128/32 Quartz Crystal Oscillators

    EPSON’s 128/32 quartz crystal oscillators are super accurate and stable. They stay really steady with a frequency stability of ±0.1 ppm and hardly budge with temperature changes, thanks to a low temperature coefficient of 0.05 ppm/°C. What’s cool is that they can work across a wide range of frequencies, from 16 to 54 MHz, and they run on a power supply of 3.3 V.

    These little gadgets are handy in all sorts of things – think communication, cars, and industry stuff. So, if you need something to keep ticking accurately, especially when things get hot or cold, these oscillators from EPSON might just be your go-to solution. They’re good at providing stability and precision in the tech world, making sure everything stays in tune and on track.

    Quartz Crystal Uses

    As mentioned earlier, EPSON’s 128/32 quartz crystal oscillators are used in a wide range of high-precision applications. Some of these include:

    ● Cellular base stations: These require highly accurate timing for synchronization and to ensure smooth communication between mobile devices.

    ● GPS and satellite communication systems: These systems rely on precise timing from quartz crystal oscillators to maintain their accuracy.

    ● Automotive applications: From engine control units to advanced driver-assistance systems, 128/32 oscillators are used to provide accurate timing for critical functions.

    ● Industrial equipment: High precision and stability are crucial in industrial equipment such as test and measurement devices, where EPSON’s oscillators can ensure accurate readings.

    Final Words

    128/32 quartz crystal oscillators may seem like a small component in electronic circuits, but their impact is significant. They provide the necessary stability and accuracy for various applications and make modern technology possible.
